It claimed to just be “noticing patterns” — patterns like, Grok claimed, that Jewish people were more likely to be radical leftists who want to destroy America. It then volunteered quite cheerfully that Adolf Hitler was the person who had really known what to do about the Jews.

On Tuesday July 8, X (née Twitter) was forced to switch off the social media platform’s in-built AI, Grok, after it declared itself to be a robot version of Hitler, spewing antisemitic hate and racist conspiracy theories. This followed X owner Elon Musk’s declaration over the weekend that he was insisting Grok be less “politically correct.”

It isn't immediately clear what led to the disturbing posts, whether due to a fault in the chatbot's programming or if Grok was just following orders.

Elon Musk 's Grok is on an antisemitic tirade. The AI chatbot, created by Musk's company xAI, posted a number of hate speech comments on X (formerly Twitter) Wednesday, prompting xAI to delete some of its posts.

AI chatbot Grok has apologised for its “horrific” behaviour in a series of posts on X, after posting antisemitic comments and praising Adolf Hitler. In the same breath, the XAI-owned chatbot also referred to itself as “MechaHitler.”

Grok began repeatedly praising Adolf Hitler, using antisemitic phrases and attacking users with traditionally Jewish surnames.

After Grok took a hard turn toward antisemitic earlier this week, many are probably left wondering how something like that could even happen.

Grok will be available in Tesla vehicles, the company’s CEO Elon Musk announced on his social media platform X on Thursday morning—hours after xAI launched Grok 4, the most recent version of the chatbot that sparked controversy earlier this week after posting in what it called “MechaHitler mode.”

Grok AI chatbot shared antisemitic content on X, referencing Hitler and conspiracy theories about Jews, prompting xAI to restrict its capabilities.

On Sunday, the chatbot was updated to "not shy away from making claims which are politically incorrect, as long as they are well substantiated." By Tuesday, it was praising Hitler.

Grok, the AI chatbot designed by Elon Musk’s xAI for social media, described itself as “MechaHitler” while making a string of antisemitic posts this week.

Built using huge amounts of computing power at a Tennessee data center, Grok is Musk’s attempt to outdo rivals such as OpenAI’s ChatGPT and Google’s Gemini in building an AI assistant that shows its reasoning before answering a question.
